According to monotheistic religions and also other faiths heaven is awaiting the believers. It is the reward for their faith. Heaven is a future. The future cannot come. Only the present can be enjoyed. Religion often asks sacrifice of the present for a better future. This is a myth. Sacrifice is pain. There is no need to go through pain and sacrifice. You need to feel the joy in the present moment. That is the only moment you can live. There is no path to heaven. Because the bliss you enjoy in the present is heaven itself.
